Abstract

Stoichiometric homeostasis is the ability of life to maintain inner chemical constancy despite changes in the environment and resources. Organisms can be stoichiometrically homeostatic to different degrees. This variation can be substantial even within species, but is ignored in most studies of ecological stoichiometry. Recent studies suggest that resource limitations are an important selective pressure behind homeostasis, but are contradictory in direction, likely owing to differences in nutrient storage strategies. Understanding the selective pressures underlying stoichiometric homeostasis, and its potential for rapid evolution, are key to predicting eco-evolutionary dynamics. This calls for the development of an evolutionary theory of stoichiometric homeostasis that incorporates rapid evolution, as well as for empirical studies to test the underlying mechanisms.

生态平衡的生态进化动态。
化学平衡是指生命在环境和资源发生变化的情况下仍能保持内在化学稳定性的能力。生物可在不同程度上实现化学计量平衡。即使在物种内部,这种差异也可能很大,但大多数生态计量学研究都忽略了这一点。最近的研究表明,资源限制是平衡背后的一个重要选择压力,但在方向上却相互矛盾,这可能是由于营养储存策略的差异造成的。了解生态平衡背后的选择压力及其快速进化的潜力,是预测生态进化动态的关键。这就需要发展一种包含快速进化的计量平衡进化理论,并开展实证研究以检验其基本机制。

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
